DHAKA, Bangladesh (CNN) -- Army convoys are combing areas around the Bangladeshi border guard headquarters, vowing to punish participants in this week's bloody mutiny, which killed nearly 100 army officers and civilians, according to The New Nation newspaper.

Bangladeshi firefighters continued to uncover bodies Friday of Bangladesh Rifles officers from a mass grave.

More than 160 army officers were inside the headquarters of the Bangladesh Rifles (BDR) when the mutiny broke out on Wednesday morning, local reports said.

So far, 88 bodies have been recovered from mass graves in the outskirts of Dhaka, the newspaper reported.

At least 22 bodies have also been recovered from the Buriganga River after the rebelling troops dumped them down a sewer during the standoff, authorities said.

The 88 found dead were among those 169 officers, the newspaper reported. Another 27 emerged from their captivity in the headquarters of the BDR, a 65,000-strong paramilitary outfit primarily responsible for guarding the country's borders. About 200 BDR soldiers have been arrested.
